The diagnostic value of exploratory tympanotomy in sudden sensorineural hearing loss remains controversial. This study and review were performed to identify the incidence of perilymphatic fistula in patients with sudden sensorineural hearing loss. The effectiveness of tympanotomy for sealing of the cochlear windows in cases with perilymphatic fistula was evaluated.
A search in common databases was performed. Overall, 5034 studies were retrieved. Further, a retrospective analysis on 90 patients was performed.
Eight publications dealing with tympanotomy in patients with sudden sensorineural hearing loss were identified. In 90 patients diagnosed with sudden sensorineural hearing loss and undergoing exploratory tympanotomy, 10 patients (11 per cent) were identified with a perilymphatic fistula, and this corresponds to the results obtained from our review (13.6 per cent).
There was no significant improvement after exploratory tympanotomy and sealing of the membranes for patients with a definite perilymphatic fistula.
探索性鼓室切开术在突发性感音神经性听力损失中的诊断价值仍存在争议。本研究及综述旨在确定突发性感音神经性听力损失患者中内淋巴瘘的发生率。评估鼓室切开术对有内淋巴瘘病例封闭耳蜗窗的有效性。
在常见数据库中进行检索。共检索到5034项研究。此外，对90例患者进行了回顾性分析。
确定了8篇关于突发性感音神经性听力损失患者鼓室切开术的文献。在90例被诊断为突发性感音神经性听力损失并接受探索性鼓室切开术的患者中，10例（11%）被发现有内淋巴瘘，这与我们综述的结果（13.6%）相符。
对于明确有内淋巴瘘的患者，探索性鼓室切开术及封闭膜后并无显著改善。
